Foam injection molding device

Abstract

The invention belongs to the technical field of foam production, and particularly relates to a foam injection molding device. The foam injection molding device comprises a device main body, the upperend face of the device main body is provided with a feeding hopper, the lower end of the device main body is fixedly connected with a control box, the lower end of the inner wall of the control box isdetachably connected with a fixing plate through bolts, the upper end face of the fixing plate is fixedly connected with a hollow cylinder, the inner wall of the hollow cylinder is provided with a gear, the outer side wall of the gear meshes with a rack, the upper end of the rack penetrates through the hollow cylinder and the control box and extends into the device main body, a bottom plate is fixedly mounted at the upper end of the rack, and a rotating shaft is fixedly connected to the outer side of the gear. Foam is poured into the device main body through the feeding hopper, then the device main body is heated to make the inner wall of the device dissipate heat, then the rotating shaft is enabled to rotate to drive the gear to rotate, then the rack and a bearing plate are driven to move upwards, then the bottom plate upwards extrudes the foam, the foam is melted and adhered to form a foam plate under the condition of extrusion and heating, so that the effect of achieving manufacturing of a small product is achieved.

Description

technical field [0001] The invention relates to the technical field of foam product production, in particular to a foam injection molding device. Background technique [0002] Foam injection molding machine is a mechanism that puts foam plastic particles into the device, squeezes and heats the surrounding foam, and makes foam particles into large foam blocks under high temperature and high pressure. [0003] Existing foam injection molding devices are generally large in size and complex in structure. After making large foam compression blocks under high temperature and high pressure, the foam blocks are then cut into different shapes by cutting methods. The cut products tend to have burrs, which will damage the shape of the product. , so that it is not convenient for the production of small foam board products, and it does not have the characteristics that can be used by people of different ages. Contents of the invention [0004] In order to solve the problems raised in ...
